THE GRWSTORYIt all began in 1989, when Gerrie van der Merwe, then a leading lecturer in
Advanced Mathematics, took a bold step having identified a career opportunity
at his brother-in-law’s Worcester based transport business, Wynland Vervoer.
Three fruitful years of committed involvement soon became a family affair.
His sons Gerhard and Wentzel would too join the business, bringing along
their business associate and friend, Rossouw van Eeden.
Within a matter of months, the entrepreneurial trio, having discerned a
cumulative plea for significant modifications to the fabrication of existing
road tankers throughout the industry, decided to utilize their engineering
expertise and design and manufacture their very own new scale model. The
result: an elevated product that would soon overshadow its competitors.
Recognising that this was just the beginning, the three went on to create
GRW (Gerhard, Rossouw, Wentzel) in 1996: a progressive manufacturing
firm whose unwavering commitment to engineering excellence will
henceforth design and manufacture world-class road tankers and transport
solutions, always superseding the highest international specifications; a
dynamic manufacturer that looks to the future, keeping pace with a rapidly
progressing industry characterized by unremitting technological change.
Headquartered in Worcester, GRW’s manufacturing complex steadily evolved
into an extensive, ultramodern production facility, employing a brilliant array of
engineers, designers, quality control checkpoints, research teams, and leading edge
fabricating, cutting, and welding lines respectively, each continually
upgraded to keep pace, if not drive, global innovation.
Through the leadership of Gerhard van der Merwe (CEO), today GRW
is a bold, formidable and ever-evolving market leader both locally
and in the UK, employing over 750 associates. Through its highly
qualified, innovative, and committed people – the foundation of its
technologically advanced production process and service excellence
– GRW guarantees the supply of a diverse range of robust, state-of-
the-art road transport solutions with extended life-cycles, augmented
by unparalleled after-sales support in harmony with worldwide
transportation innovations and standards.
KEEPING PACEWITH A RAPIDLYPROGRESSING
INDUSTRY
GRW TAUTLINERGRW employs best-practice technology and processes in their extensive ultramodern production facilities
to produce the industry benchmark for trailers. The company abides by the philosophy that the true
financial cost and benefits of a product do not lie in its initial purchase price, but more often in its cost-
effective maintenance, residual value, and life-cycle cost. An aggressive and unique approach to change in
our industry has resulted in a top-notch product – the Inkunzi tautliner trailer – whose unrivalled features
and extended lifespan are designed to meet the unique needs of specific application requirements.
Inkunzi, the bull in isiZulu, is a powerful beast. Admired, revered, feared, and respected in many
cultures, this magnificent animal has physical strength, a strong will and an uncompromising nature.
The muscle band around its neck and shoulders bolsters its imposing stature, reinforcing its appearance
of belligerence, stubbornness, and its unbending nature. The term ‘bull-headed’ is quoted with reason.
In addition to instilling confidence, the bull also symbolises stability, hard work, methodical
progress, and a rigid determination. All of these traits are to be found in the features of the
Inkunzi tautliner:
• A lighter, stronger, more durable flooring of birch plywood that is permanently flat, and easily installed.
• A modular roof structure designed for longevity and superior operational performance.
• Fully-coated, UV-resistant curtains, with strengthening webbing and high-qualit tensioners.
• A high-strength steel chassis, with a combination of welded and bolted assemblies that combats fatigue in high stress areas.
• 6-12m curtain sided interlink• 6-12m high volume curtain sided interlink• 6-12m maximizer (high volume with double stacking)• 7-11m curtain sided interlink
• 15.5m tridem semi curtain sided• 7.2m curtain sided rigid• 7.2m high volume curtain sided rigid• 9.2m high volume curtain sided rigid
CONFIGURATIONS INCLUDE:

MODULAR ROOF STRUCTURE
The patented Curtain Roller System is designed for longevity
and superior operational performance. The two vertical rollers
and one horizontal roller ensure smooth curtain operation.
The full aluminium cambered Roof Rail ensures optimum
loading height, with full-length, smooth-operating sliding side
pillars; designed to accommodate fixed or sliding roof options as
well as a lifting roof system.
CURTAINS
GRW uses fully coated and considerably more UV-resistant material than commonly used
products, offering the market ‘taut’ side curtains that are bound to last. With inner and outer
coating that preserve the plasticizer in the material to prevent it from becoming brittle; high
quality tensioners, and supplementary strengthening webbing, GRW’s curtains are better
protected against dirt, scratches, and de-pigmentation, topped with high-definition, long-
lasting and lacquered UV printing that can be custom made for various trailer brands.
GRW adds strengthening webbing to its curtains to ensureproper wind up and additional load security
GRW’s newly designed roof covers are aimed at reducing water ingress.

CHASSIS
Painstakingly designed and rigorously tested using FEA and
strain gauges, GRW’s high-strength steel chassis is designed
for reliability and modularity; with a combination of welded
and bolted assemblies that increase fatigue life in high stress
areas, and clamped peripherals for greater flexibility and ease
of replacement.
POWDER COATINGTo ensure top quality coating and the overall preservation of
your vehicle’s value in the long run, all GRW steel components
are shot blasted to the correct surface roughness before
entering the automated coating plant, where they are primed
and dried to perfection, finished with electrostatic powder
coating that is cured at 190°C to produce the best quality finish
with the highest stone-chip and rust breakthrough resistance
capabilities. The electrostatic method ensures 100% coverage
even in the smallest cavities and corners in the colour and
finish of choice.
Rubbing Plate design according to guidelines in SAE J133Better flatness over life of trailer. Less wear on 5th wheel.
